"To all whom it maty ooncermf Y,

Be it known that I, Riemann F. CORWIN, a citizen of/ the United States, vresiding at Grand. Rapids, in the county of Kent and 5 `State of Michigan, have invented certain new and useful Improvements in Vehicle-Wheels,

` which vFigure 1 is a transverse section of'lthe tire and'rrm of the wheel on the line a; a: of Fig. 4

Fig. 2 is the same showing a modjfied'form of securing the outer or steel ring of the tire to the flange; Fig. 3 .is a side view of a section of the felly showing relative size of the bolts and the bolt holes,andFig. 4 is a side e1eva' tion of` a wheel greatly reduced' in diameter b'ut with'the rim enlarged-to nearly its normal size to show the construction of its several parts.

4'Similar Lletters refer to similar parts throughoutthe several views.

:5 In the construction of this wheel I make pneumatic tube, preferably an use, first of a ordinary sing tube 'tire-j as shown at A. Around this tube I place a jacket B o fabric thatis so woven that it willstr'etch considerably, longitudinally but will not' stretch laterally. IThis'casingmay bemade by interweaving an inelastic Woof with an elastic ./W'p, a common process in the weavers art. By this means the pneumatic tube A may be *5 fully inflated so that 'it will ll the steel jacket zC solidly i and no longitudinal strain will be exercised upon the tube A by reason of the labor exercised upon the rim of the wheel when carrying a vehicle.

f) yI incase the tubes A and B in a rigid steel 5 casing C that nearly surrounds the tubes,... .n

illustrated in the accompanying drawing in1 terminating, near the inner line of the tire agroove for the reception of the felly.E,

which isheldin place by bolts F,.passing through the flanges D andftlie largehole e-in the fe ly. -The object of the hole e being so much larger than the bolt F is to give sufficient mo'vementto the felly to allow it t0` move Yto and from the pneumatic tube A, 4`the contact with' the surface of the outer tube orv with flanges D that project inward and form I router peripheryfofthe felly,'being in direct jacket B sothat any sudden jolt upon the tire H will cause'the felly to press downward upon the tubes A and'B, as indicated by the dotted. lines in Figs. '1 a'ndl2, andthus give resiliency tothe wheel,- and as the `tubes A and B cannot expand sidewiseI by-reason of being held rmly to form bly the steel casing C, the entire resilienc ,of t e wheel must be derived from' the action -ofthe fell E upon.

'lol

the narrow surface of the tire that 1s 'covered i and the degree 'of resilience is governed, `rst, by the 'rigidity of the-tire, and, second, by the '.size of the holes e 4through the felly'.

While I refer theuse'of `the auxiliaryfelly G and the iardrubber tire H the rim maybe l used without them but notvith nearly as 'good results. While the pneumatic tube A will workalmost erectly Without this casing, the wear an .strain 'is so much greaterupon it that I deem it much more touse it. Y. y I is the hub and J is the spokes of the wheel.'y

desirable Having` thus fully'described my inventionp what I claim as new anddesireto secure by Letters Patent of the United States,'is:-

1. In a vehicle wheel, a metallic casing open at the innerv periphery andhaving flanges projecting inu'rardl and small bolts passing through thm,fafellybetweensal@ flanges and havimr large 'holes therethrou h o to receive. the smallb ts, aneumatic tu e within the inclo'sure formed y the felly and the metallic casing, and n intermediate fabric casin 'woven of elastic warp-and nonelastic woo and placed aroundl-the pneumatic tube Within the metallic casing.4

2. In a vehicle wheel,- a'metallic'casing Qpenat the inner periphery and having inl Wardly proj eating flanges, gmail bots through Y having arge holes for 'the free passage of the bolts, a'pneumatic tube Within the opening formed by the fely and the met; sing, a fab'ic casing Woven with Qas'm; Warp and n0n-e1avstic Woof and placed aroum the pneumatic tube Wlthm the meaihc easing, y
